摘要:
An interface card includes data transmission routes which allow for data transmission in a plurality of data transmission modes and a mode selection switch for selecting a data transmission mode from the plurality of modes. With the interface card, a user is able to select an optimal data transmission mode for the environment.

An interface cable allows the number of components and manufacturing costs to be reduced. The interface cable has a housing defining an inner volume which has an opening. A first connector is removably connectable to one of a computer and a portable terminal. The first connector protrudes through the opening in the housing. An interface circuit is coupled to the first connector in which the interface circuit is located within the housing. A cable is coupled to the interface circuit. A second connector is removably connectable to the other of the computer and the portable terminal.

A shield case is fixed to a surface of a circuit board with a conductive joining material so as to cover a shielded portion on the circuit board surface. The shield case includes joint terminals extending outward and inclined upward from a lower edge thereof that is in contact with the circuit board surface. The joint terminals are joined to the circuit board surface with the conductive joining material provided therebetween. The shield case can thereby be fixed to the circuit board surface, and grounded to a ground portion provided on the circuit board.

In a card device having a circuit substrate housed in a card casing and an antenna disposed rotatably on the exterior of the card casing, an antenna rotary shaft composed of a conductive material is provided at the base end of the antenna. The antenna rotary shaft extends from the exterior to the interior of the card casing along a substrate surface of the circuit substrate via a through hole of the card casing in such a manner that the antenna rotary shaft is supported rotatably by the card casing while being elevated from the circuit substrate. A section of the circuit substrate that is opposed to the antenna rotary shaft has a feeding terminal fixed thereto. The feeding terminal has a pair of antenna-rotary-shaft elastically-pressing portions that sandwich and electrically contact the antenna rotary shaft from opposite sides with elastic forces in a surface-contact fashion.

A card device includes a card casing accommodating a circuit board. The card device is capable of being inserted into and pulled out from a card slot in an apparatus in which the card device is to be mounted. An anti-slipping member is anchored and exposed at a rear-end wall portion of a peripheral wall of the card casing for being held at least when the card device is inserted or pulled out. The rear-end wall portion is positioned at a rear end of the card device opposite to the end of the card device that is inserted into the card slot.

A card-type device that includes an antenna body disposed on a housing and movable along a turning shaft between an upright position and a flat position. An antenna turning member applies an urging force to the antenna body in a direction in which the antenna body turns to the upright position. A locking projection projecting and a corresponding locking portion which is fitted to the locking projection when the antenna body is in the flat position, stops the antenna body from turning. When the antenna body moves in a direction in which the antenna body is to be unlocked, the locking projection is released from the locking portion, and the antenna body automatically turns toward the upright position by the urging force of the antenna turning member.

A card device includes a card case, a circuit board disposed in the card case, and an antenna rotatably disposed on the outside of the card case. An antenna rotating shaft is disposed on the base end of the antenna and inserted from the outside into the inside of the card case through a through-hole of the card case such that the antenna rotating shaft extends along the surface of the circuit board and is supported within the card case with the inner part of the antenna rotating shaft being spaced apart from the circuit board and the antenna rotating shaft being freely rotatable. A feed terminal having elasticity that urges the feed terminal against the antenna rotating shaft is disposed between the antenna rotating shaft and a part of the circuit board facing the antenna rotating shaft. The feed terminal is fixed to an antenna connection part of a circuit formed on the circuit board facing the antenna rotating shaft. The feed terminal is urged by its elasticity into contact with the antenna rotating shaft.

An information card includes a ground plate that is connected to a ground conductor portion of a printed substrate and is integral with an external panel. Plural contacts are provided with the ground plate, and are exposed at the upper side out of windows provided in the external panel. Lead terminals are extended from the ground plate and are integral therewith, and the tips of the lead terminals are soldered to the ground conductor portion of the printed substrate.
